3456 cubic inches to cubic ft The lesson is Multiple unit multipliers.

Mathematics
1 answer:
Dafna1 [17]2 years ago
3 0

Answer:

Step-by-step explanation:

1 cubic foot is 12 * 12 * 12 cubic inches.

1 cubic foot = 1728 cubic inches.

1 cubic foot = 1728 cubic inches

x cubic feet = 3456                            Cross multiply

1728 x = 3456 * 1                                Divide by 1728

x = 3456/1728

x = 2  cubic feet.

The other way  to do this is

3456 cu inches [1 cubic Foot/1728 cubic inches] note that the units cancel and you are left with 1 division problem.

The question still comes to 2.

Ivan finished Four-fifths of his math homework problems and all 3 problems for his science homework before dinner. If he finishe
valentinak56 [21]

Answer:

Step-by-step explanation:

Since we know that Ivan finished all his science problems (3) we know that there are only math problems remaining

substract the science problems from the total 43-3=40

And now we can determine the amount of math problems

4/5 = 40/x where x is the total amount of math problems Ivan was assigned

cross multiply

4x = 5*40

4x=200

isolate the variable

4x/4 = 200/4

x=50

So Ivan was assigned a total of 50 math problems

(Note*) since there are 40 math problems finished 40/50 is equal to 4/5. Just a tip if you don't want to do the whole calculation

Hope this helps!
